MRI Quality Assurance Phantom MHR
This QA phantom for MRI allows evaluation of slice thickness, spatial resolution, uniformity and geometric distortion as well as contrast
Features
- Uniformity is maintained under the high magnetic field of 3.0 Tesla
- Uniformity provides high precision evaluation for other parameters
- Complies with NEMA and AAPM standards
Evaluation Parameters
- Signal-to-noise ratio (SNR)
- Image uniformity
- RF uniformity
- Spatial resolution
- Spatial linearity (image distortion)
- Slice thickness
- Slice position/separation
- Image contrast
- Image artifact

MRI QA System
The combination of a QA phantom and image scoring software in a complete set introduces a new approach for MRI QA. Tests can be carried out in a very efficient and time saving manner. The acquired test images are loaded into the software where the test procedure in concluded with only a few clicks.
Ongoing image QA tests assure consistent image quality over a long period of time. The test results will reveal deterioration in the system performance thus identifying potential malfunctions which may be a risk to the integrity of the imaging system and consequently a risk to patient safety and health.
Parameters:
- Signal-to-noise ratio
- Uniformity
- Slice thickness in 2D
- 2D Geometric distortion
- Spatial resolution
- Ghosting artefacts
